大乘法苑義林章 7.33

7.33

第五事業者，其佛法身或唯自利，為二身依。或通二利，自受用身唯有自利；若他受用及變化身，唯屬利他，為他現故。《佛地經》云「作諸眾生一切義利，佛雖寂定，由先所修加行願力，任運能作一切有情一切義利。他受用土中多說妙法，少作神通，作利十地菩薩義利。變化土中多作神通，少說妙法，作利三乘一切義利。」

Fifth, activities: The Buddha's dharmakāya either solely benefits oneself, serving as the basis for the other two bodies, or pertains to both benefits. The self-enjoyment body has only self-benefit; while the other-enjoyment and transformation bodies pertain solely to benefiting others, because they are manifested for others. The Buddhabhūmi-sūtra says: "Accomplishing all benefits and advantages for all sentient beings. Although the Buddha is in quiescent concentration, through the power of previous practice and vows, he spontaneously accomplishes all benefits and advantages for all sentient beings. In the other-enjoyment land, he mostly expounds the wondrous Dharma and rarely performs supernatural powers, bringing benefit to the bodhisattvas of the ten grounds. In the transformation land, he mostly performs supernatural powers and rarely expounds the wondrous Dharma, bringing all benefits to the three vehicles."
